Hybrid beluga whale optimization algorithm with multi-strategy for functions and engineering optimization problems

Journal of Big Data
Beluga Whale Optimization (BWO) is a new metaheuristic algorithm that simulates the social behaviors of beluga whales swimming, foraging, and whale falling. Compared with other optimization algorithms, BWO shows certain advantages in solving unimodal and

Cementum structure in Beluga whale teeth [PDF]

Acta Biomaterialia, 2017
A large fraction of the volume of Beluga whale (Delphinapterus leucas) teeth consists of cementum, a mineralized tissue which grows throughout the life of the animal and to which the periodontal ligaments attach. Annular growth bands or growth layer groups (GLGs) form within Beluga cementum, and this study investigates GLG structure using X-ray ...

Year-Round Dive Characteristics of Male Beluga Whales From the Eastern Beaufort Sea Population Indicate Seasonal Shifts in Foraging Strategies

Frontiers in Marine Science, 2022
Dive behavior represents multiple ecological functions for marine mammals, but our understanding of dive characteristics is typically limited by the resolution or longevity of tagging studies.

The T‐Cell Response Mechanism in Human Papillomavirus‐Associated Cervical Cancer and New Strategies for Immunotherapy

iNew Medicine, EarlyView.
ABSTRACT Human papillomavirus (HPV) is a double‐stranded DNA virus that infects human skin and mucosal tissues exclusively. The German scientist Harald zur Hausen was awarded the 2008 Nobel Prize in Physiology or Medicine for his discovery of the link between HPV infection and cervical cancer.

Photographic evidence of tagging impacts for two beluga whales from the Cumberland Sound and western Hudson Bay populations

Arctic Science, 2022
Beluga whale (Delphinapterus leucas (Pallas, 1776)) movements, habitat use, and diving behaviour have been studied using satellite-linked transmitters for decades.

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Development of Beluga, Delphinapterus leucas, Capture and Satellite Tagging Protocol in Cook Inlet, Alaska [PDF]

, 2000
Attempts to capture and place satellite tags on belugas, Delphinapterus leucas, in Cook Inlet, Alaska were conducted during late spring and summer of 1995, 1997, and 1999. In 1995, capture attempts using a hoop net proved impractical in Cook Inlet.

Optimal Configuration of Distributed Generation Based on an Improved Beluga Whale Optimization

IEEE Access
Large-scale distributed generation (DG) access to the distribution network brings many uncertainties to the distribution network, considering the impact of different types of distributed power supply on the optimization results as well as the uncertainty

Secularism, Gender and Masculinity in Nineteenth‐Century Cremation in Europe and the USA

Gender &History, EarlyView.
ABSTRACT This essay explores, from transnational perspectives, the early history of modern cremation, which developed in the long nineteenth century with secularist connotations. I argue that the beginnings of modern cremation were shaped by bourgeois men who claimed certain identifiers for themselves in a gendering and Othering way.
